This product will allow you to install wheels on your heaviest and bulkiest construction barriers, enabling your craftsmen or yourself to access the site! Unlike classic white nylon wheels, these adapt according to the diameter of the tube, and rolling is greatly facilitated by the internal ball bearing with a waterproof cover.
All you need to do is place the support at the base of your tube and tighten it using the nuts and bolts to attach the assembly. Once tightened, it is impossible to loosen it without keys due to the presence of nylstop. Generally, the diameter is 42 mm on most barriers.
